Abstract: This work is devoted to the study of processes influencing the performance of functional antifouling polymer brush coatings and their interactions with complex biological media. Specifically, both results of the fundamental and applied research on the i) functionalization processes influencing coating resistance, ii) tailoring of the physico-chemical properties of the antifouling coatings to minimize the nonspecific interactions with complex biological samples, and iii) behavior and performance of the polymer brush coatings in varying environments are presented. Acrylamide and methacrylamide-based polymer brushes with side hydroxyl, carboxybetaine, and sulfobetaine groups were studied, showing the great potential of their optimized copolymer structures as tunable antifouling functionalizable platforms for cell research or biosensor applications. Moreover, newly developed procedures for antifouling properties recovery after EDC/NHC...
